Novel torpedo anchor with expandable anchor head and installation method of novel torpedo anchor

Abstract

The invention discloses a novel torpedo anchor with an expandable anchor head. The novel torpedo anchor mainly comprises the anchor head composed of four conical plates, a guide rod, an anchor body, an anchor tail cover plate, a mooring ring and the like, wherein the four conical plates in the anchor head are hinged with the lower edge of the anchor body; the lower ends of the conical plates are connected with a steel cable; the steel cable is guided to the other end through a pulley on the anchor body and is tied to the mooring ring; and when the anchor body penetrates to a specified depth, the conical plates can be expanded by pre-tensioning the guide rod. By expanding the conical plates of the anchor head of the torpedo anchor, the stressed area of the anchor body is increased, therebyenhancing the bearing capacity of the anchor body; a tensioning device is relatively simple and easy to manufacture; and installing and tensioning processes are relatively simple and easy to operate.

Description

technical field [0001] The invention relates to a torpedo anchor and an installation method thereof, in particular to a novel torpedo anchor with an expandable anchor head and an installation method thereof. Background technique [0002] In recent years, more and more floating structures (floating platforms and ferries, floating trestles, floating wharves, etc.) have been used for marine resource development, construction of remote islands and reefs, and transportation of near-shore personnel and materials. Floating structures can adapt to the complex and changeable marine environment and geological conditions, and its mooring positioning technology is the key to its full effectiveness, which has attracted extensive attention from researchers in the marine engineering field. Among them, the torpedo anchor foundation (torpedo anchor) is the latest development of a new type of anchoring technology, which has the characteristics of simple and efficient installation, low cost, a...

AI Technical Summary

Problems solved by technology

[0003] The installation of the torpedo anchor is quick and easy. It only needs to be lifted in the water for a certain distance from the mud surface, and then the anchor body is released. The anchor body relies on its own weight to penetrate into the soil. For its frictional resistance, the bearing capacity can only be exerted to a limited extent. In order to increase the stress area of ​​the anchor body and increase the bearing capacity, a new type of torpedo anchor with an expandable anchor head is proposed.
